1. TV Not Powering On

One of the most common issues we handle in Donholm is TVs refusing to power up.

Technical Breakdown:

• Faulty Power Supply Board – The SMPS (Switched Mode Power Supply) converts AC mains into low voltage DC required by the TV’s circuits. A blown capacitor, faulty MOSFET, or burnt resistor in this board can stop the TV from turning on.
• Damaged Power Cable or Plug – Sometimes the issue is as simple as a broken cord.
• Main Board Faults – If the motherboard fails, power signals are not processed correctly.

Solutions by Refitec:

• Testing and replacing faulty capacitors or ICs.
• Replacing damaged power boards with genuine spare parts.
• Full circuit diagnostics using advanced tools.

Maintenance Tip:
Always use a surge protector or stabilizer to prevent damage from Nairobi’s frequent power fluctuations.

2. TV Has Sound but No Picture

This problem is widespread among LED and LCD TVs.

Technical Breakdown:

• Backlight Failure – LED strips behind the panel burn out.
• Inverter Board Failure – Converts power for the backlight system.
• T-CON Board Fault – Transfers image signals to the display.

Solutions by Refitec:

• Replacing faulty LED backlight strips.
• Repairing or replacing the inverter board.
• Testing and replacing T-CON boards.

Diagram-style Explanation (Simplified):
Power Supply → Main Board → T-CON Board → LCD Panel + Backlight.
If backlight fails, the image is still there but invisible without light.

Maintenance Tip:
Lower your TV brightness settings to extend LED backlight life.

4. Lines on the Screen (Vertical or Horizontal)

Technical Breakdown:
